S series helical worm gear motor

S series is one kind of Helical worm gearbox, designed as Modularization and high-stainless cast iron case. It is combination of helical gear and worm gear, which with higher efficiency and strength than simple aluminum alloy worm gearbox. Due to their outstanding efficiency, these drives can be used in every industrial sector and tailored to individual torque and speed requirements. The gear ratios afforded by the helical-worm gear stage and the low noise levels during operation make these gearmotors ideal low-cost solutions for simple applications.
